What this 6.8 µH shielded inductor brings to the rail
The Murata DFE322512F-6R8M=P2 is a shielded wirewound power inductor in the DFE322512F series, built around a metal composite core that keeps saturation soft and predictable. Rated 1.2 A continuous with a saturation current of 2 A, it delivers 6.8 µH ±20% — the margin between rated and saturation current gives a headroom buffer for transient loads that spike above the DC bias.
Board-fit and footprint constraints
The 220 mOhm max DC resistance sets the I²R loss floor — at 1.2 A the copper loss is roughly 317 mW, a figure the layout copper pour and via stitching must sink without raising the core temperature above the 125°C ceiling.
The shielding reduces radiated EMI into adjacent traces, which matters when the inductor sits near a sensitive analog front-end or RF section on the same board edge.
